Description
1. Overview of Water Pressure Reducing Valve
The VTON water pressure reducing valve is designed to regulate high water pressure and stabilize downstream pressure in cold and hot water systems. Using advanced hydraulic principles, it directly senses downstream pressure through a diaphragm, adjusting the valve disc’s opening to achieve precise pressure reduction and stabilization.
These valves are suitable for urban and high-rise building systems, replacing traditional water partitioning pipelines, and playing a critical role in reducing pressure in conventional water networks.
2. Key Features
- Innovative Structure: Utilizes advanced hydraulic principles for precise control.
- Stable and Reliable: Ensures smooth operation with high flow capacity.
- Water Hammer Prevention: Features quick opening and slow closing mechanisms to avoid water hammer impacts, with adjustable closing times.
- High Precision: Offers accurate pressure reduction and stabilization across a wide adjustment range.
- Long-lasting Performance: Excellent sealing capabilities and extended service life.
- Ease of Use: Designed for simple installation, adjustment, and maintenance.
